Extinction
Disruption of Contingency
Unreinforced responses needed
Operant Extinction
Increase Response Effort to
Speed Up Extinction
Reinforcers Freely Available
NCR (Non-contingent Reinforcement)
Is there an extinction burst in NCR?
No extinction burst in NCR
Increased rate and intensity after non-reinforcement

Contingent Withdrawal of Attention: Extinction?
Not Extinction
Required for Extinction to Work
Unreinforced responses
Precludes Extinction
Blocking

All or Nothing Responding
Fixed Ration Responding
Scalloped Responding
Fixed Interval Responding
Smooth, high rate responding
VR and VI Responding
Respond where reinforcement is greatest
Matching
Every response is reinforced
Continuous Reinforcement (CRF)
Not every response is reinforced
Intermittent Reinforcement
SR+ after same # of responses every time
Fixed Ratio
SR+ after same # of responses on average
Variable Ratio
SR+ after same time passes +1 response
